Product information

Whether you're a recreational boat owner or a busy professional, choose the engine that will help you get more out of your boat.

Every engine in the Yamaha range uses the very latest Yamaha marine technologies, engine layouts and ingenious intake and exhaust systems. Efficient performance is ensured by a system of micro-computer controls that precisely monitor the engine – from fuel mixture to combustion efficiency and maintenance scheduling.
And, without compromising on power, performance or usability, our specially designed marine engines also help preserve the environment through the use of pioneering clean-burn technologies. 



Fresh Water Flushing system

An easy-access, front-mounted connector allows you to easily flush salt and dirt from the waterways without having to run the engine: just connect a hose and you're ready to go. This is a very efficient way to reduce corrosion and extend the life of your outboard.

High-output alternators

Never get left short of Amps. A High-output alternator ensures that power is always available to start the engine – even after prolonged periods of idling or when you've been running at low revs while using multiple electrical accessories.


Yamaha's exclusive PrimeStart™ system makes starting your outboard engine as easy as starting your car – even from cold. It's comforting to know that with either the Electric or Manual Start, your engine will fire first time. Every time.

Shallow Water Drive system

Cruise towards the shore with confidence thanks to Yamaha's Shallow Water Drive system. It offers ample protection for your propeller and allows you to 

'Start-in-gear' protection

With this kind of power, an unintentional pull-away can be a stressful experience. So Yamaha's 'Start-in-gear' protection prevents the possibility. On Manual Start models, the starter is locked when any gear other than Neutral is engaged. On Electric Start versions, the power supply to the starter motor is isolated until Neutral is selected.
